A piece of legislation that called for popular sovereignty to decide the slavery issue was
1)the Fugitive Slave Act.
2)the Missouri Compromise.
3)the Kansas-Nebraska Act.
4)the Compromise of 1850.
The Kansas Nebraska act was made because the current states couldn't decide if new states coming into the union should be free states or slave states. The Kansas-Nebraska act set up Kansas and Nebraska as states and allowed them to vote on the issue.
